One of steel structure’s system for resist lateral loads on building is Buckling Restrained Braced Frame (BRBF). This system is development from system Concentric Braced Frame (CBF). These system rely on brace element for disipation earthquake energy. The differences of these system on compression strength, the failure of CBF when resist axial compression determined by buckling behavior. This condition which is developed for system BRBF. The main problem will be discussed on this final project are performance study of BRBF system for high building with comparison of two brace location. First location at perimeter and other as core. The parameter will be used to compare are brace yielding formation and maximum story drift. At planning and design process for brace element refer to code AISC 341-10 Seismic Provision for Structural Steel Building. With experimental study of G-Series which done at University of California. The result of this experiment used as reference for material and backbone curve which is used at performance analysis. Performance analysis will be used are pushover analysis and Non Linier Time History Analysis (NLTHA) with Northridge’s earthquake as reference load. The result will be seen are comparison of those models and also compare the final result from those methods. Then the respons of structure will be known the effect from static load and dinamic load. The result from pushover analysis shows that the two model gives a result similar. It shown from base shear capacity and drift for each view so close. But the result from NLTHA gives performance that different for the two model. This is caused by the stiffness of structure that influenced by orientation of column. Comparison between pushover analysis and NLTHA gives performance that dinamic load is more danger for the two models. Drift from NLTHA is bigger than pushover analysis. So, to decide the structures performance determined from NLTHA. Basically the performance from those two models are same. There is no significant differences from the result of analysis. Then to decide the location of brace is needed other parameter, for example space utilization. Then, model's one which the location at perimeter can be said that is better location.
